What's the difference between a welder qualification test and a WPQR?
A Welder Qualification Test (WQT) demonstrates a welder’s ability to produce sound welds by following a procedure, much like qualifying a chef’s cooking skills. In contrast, a Welding Procedure Qualification Record (WPQR) validates the welding process itself, similar to qualifying a recipe to ensure it produces consistent results. In short, WQT qualifies the person, while WPQR qualifies the method; two different but equally essential certifications.
- WQT (Welder Qualification Test):
- Assesses welder’s individual skill
- Demonstrates ability to produce quality welds
- Qualifies the person
- WPQR (Welding Procedure Qualification Record):
- Proves the welding procedure is fit for service
- Ensures consistency and reliability
- Qualifies the method
- Both are required for full compliance and quality assurance
| Certification | Focus | Purpose |
|---|---|---|
| WQT (Welder Qualification Test) | Welder’s individual skill | Qualifies the person |
| WPQR (Welding Procedure Qualification Record) | Welding process/procedure | Qualifies the method |
